Paradox #1
Ecclesiastes 3:12 talks about being happy and doing good in life. A contradiction might arise if this advice is seen as being too simplistic or ignoring life's complexities, where happiness and doing good aren't always easy or aligned. Some might see it as inconsistent with situations where doing good doesn't lead to personal happiness, creating a conflict between self-interest and altruism.
